DETAILED DESCRIPTION OF THE INVENTION

The aforementioned and further advantages and features of the present invention will be understood by reference to the description of the preferred embodiment in conjunction with the accompanying drawings where the components are illustrated based on a proportion for explanation but not subject to the actual component proportion.

Referring to FIG. 1 to FIG. 14, a composite material based building material structure is provided in accordance with the present invention. Therein, a first embodiment of the present invention is shown in FIG. 1 to FIG. 4; a second embodiment of the present invention is shown in FIG. 5 to FIG. 7; a third embodiment of the present invention is shown in FIG. 8 to FIG. 10; and a fourth embodiment of the present invention is shown in FIG. 11 to FIG. 13.

Referring to FIG. 1 to FIG. 4, in the first embodiment of the present invention, a composite material based building material structure 100 comprises a metal member 10 and a combination member 20.

The metal member 10 is formed in a bar shape. In a preferred embodiment, the metal member 10 is an extrusion of aluminum alloy, with a surface thereof being anodized to form an antioxidant layer thereon, such that the metal member 10 possesses anti-corrosion property. In detail, the metal member 10 comprises a connection plate 11 and two lateral plates 12 disposed on two ends of the connection plate 11. The two lateral plates 12 extend toward an identical side of the connection plate 11, such that a combination groove 13 is formed by the connection plate 11 and the two lateral plates 12. Referring to FIG. 1 and FIG. 3, a sectional profile of the combination groove 13 is formed in a U shape, with one side thereof open and the other side thereof closed. The metal member 10 further comprises a plurality of first connection portions 14. Each first connection portion 14 is disposed on an outer periphery of the lateral plate 12.

The combination member 20 is an extrusion of wood plastic composite. The combination member 20 in accordance with the present invention possess a wood-like appearance and several preferred characteristics, such as waterproof, moisture-proof, fireproof, and insulant characteristics, such that structural performance of the combination member 20 is prevented from deterioration under humid environment. Referring to FIG. 2 and FIG. 3, the combination member 20 comprises a recess 21. The metal member 10 is received in the recess 21 of the combination member 20. The combination member 20 comprises a plurality of second connection portions 22 disposed on an inner periphery of the recess 21. Each second connection portion 22 correspondingly receives one first connection portion 14, such that the combination member 20 is stably mounted on an outer side of the metal member 10.

In detail, the first connection portion 14 and the second connection portion 22 are corresponding combination structures which emit a sound upon engagement. Each lateral plate 12 resists against the inner periphery of the recess 21 of the combination member 20. In a preferred embodiment, each first connection portion 14 is a protruding portion disposed along a longitudinal direction of each lateral plate 12, and each second connection portion 22 is a concave portion corresponding to the protruding portion. When the first connection portions 14 and the second connection portions 22 are engaged, a sound is emitted by a collision of the first connection portion 14 and the second connection portion 22, which indicates a engaged and locked status between the first connection portion 14 of the metal member 10 and the second connection portion 22 of the combination member 20 for avoiding disengagement between the metal member 10 and the combination member 20.

Notably, each first connection portion 14 comprises two inclined sections 141. A first end of each inclined section 141 is connected with the lateral plate 12, and second ends of the two inclined sections 141 are connected with each other. The two inclined sections 141 include an acute angle therebetween. Each first connection portion 14 comprises a central line L, which passes through a junction of the second ends of the inclined sections 141 and is perpendicular to each lateral plate 12. An included angle θ between the central line L and one inclined section 141 is equal to an included angle θ between the central line L and the other inclined section 141. Therefore, the metal member 10 is engaged with the recess 21 of the combination member 20 selectively in a first engagement status or a second engagement status, as shown in FIG. 1 and FIG. 4, and each first connection portion 14 is received in the corresponding second connection portion 22.

Referring to FIG. 1 and FIG. 3, in the first engagement status, the metal member 10 is connected with the combination member 20, with the combination groove 13 of the metal member 10 facing the recess 21 of the combination member 20, such that the combination groove 13 of the metal member 10 communicates with the recess 21 of the combination member 20. In addition, an opening of the combination groove 13 is enclosed in an inner periphery of the combination member 20, and the connection plate 11 of the metal member 10 does not protrude from the combination member 20. Referring to FIG. 4, in the second engagement status, the metal member 10 is connected with the combination member 20, with the opening of the combination groove 13 and an opening of the recess 21 facing an identical direction. Hence, the metal member 10 in accordance with the present invention is engaged with the combination member 20 in selective engagement statuses according to usage demand, providing a variation of utility.

Referring to FIG. 5 to FIG. 7, a composite material based building material structure 200 is provided in accordance with the second embodiment of the present invention. The difference between the first embodiment and the second embodiment lies in that a metal member 10′ of the second embodiment is combined with two combination members 20′. In detail, the metal member 10′ comprises two connection plates 11′ and two lateral plates 12′ connected with two ends of the two connection plates 11′, wherein the metal member 10′ forms a combination groove 13′ by the connection plates 11′ and the lateral plates 12′. A sectional profile of the combination groove 13′ is formed in an enclosed rectangular shape. In a preferred embodiment, the combination groove 13′ of the metal member 10′ provides a space for housing wires and pipes; therefore, circuit design and piping design are also facilitated, in which the wires and pipes are disposed inside the metal member 10′ and prevented from damages.

Referring to FIG. 5 to FIG. 7, the combination members 20′ are connected and facing each other, such that an accommodation space 23′ is formed between two recesses 21′, and the metal member 10′ is received in the accommodation space 23′ of the two connection member 20′. The combination groove 13′ and the accommodation space 23′ are arranged in axial alignment. Each first connection portions 14′ of the metal member 10′ is received in the corresponding second connection portions 22′ of the combination members 20′. In the embodiment, an imaginary line D is defined between the two combination members 20′. The imaginary line D passes through connected positions of the two combination members 20′, and is perpendicular to lateral plates 12′ of the metal member 10′; therefore, the two combination members 20′ are mounted on an outer periphery of the metal member 10′ and covers the metal member 10′. Hence, the metal member 10′ is isolated from external atmospheric moisture and prevented from possible corrosion, thereby increasing the life span of the building material structure 200.

Referring to FIG. 8 to FIG. 10, a composite material based building material structure 200 is provided in accordance with the third embodiment of the present invention. The difference between the second embodiment and the third embodiment lies in that the third embodiment further comprises a connection member 30′ and two fixation members 50′.

The connection member 30′ is formed in a rectangular column and connected with the metal member 10′. In various embodiments, two metal members 10′ are provided, and the connection member 30′ comprises a first connection section 31′ and a second connection section 32′ integrally formed with each other. The connection member 30′ comprises a holding plate 33′ disposed between the first connection section 31′ and the second connection section 32′. The holding plate 33′ protrudes on two sides of the connection member 30′. The connection member 30′ further comprises an interior space 34′ passing through the first connection section 31′ and the second connection section 32′ in a coaxial direction thereof.

Referring to FIG. 9 and FIG. 10, the first connection section 31′ of the connection member 30′ passes through a combination groove 13′ of one metal member 10′, and the second connection section 32′ of the connection member 30′ passes through a combination groove 13′ of the other metal member 10′, such that the two metal members 10′ are connected with each other on the holding plate 33′ of the connection member 30′. The interior space 34′ of the connection member 30′ communicates with the combination groove 13′ of each metal member 10′. Subsequently, two combination members 20′ are combined with the periphery of the corresponding member 10′ and resists against the holding plate 33′ of the connection member 30′, such that the connection member 30′ is internally disposed between the metal members 10′ and the combination members 20′. Thus, a possibility of prolonging length of the building material structure 200 is achieved.

The two fixation members 50′ are mounted on an outer side of each combination member 20′ and connected between the two neighboring combination members 20′. Referring to FIG. 9 and FIG. 10, each fixation member 50′ comprises a fixation portion 51′ and two positioning portions 52′ disposed on two sides of the fixation portion 51′. Each positioning portion 52′ extends toward one side of the fixation portion 51′. In the third embodiment, each fixation member 50′ is mounted on the combination members 20′ with fixation portion 51′ and positioning portion 52′ resisting against an outer periphery of combination member 20′, such that the two fixation members 50′ are close to and resist against each other, and each fixation portion 51′ is disposed perpendicular to an imaginary line D of each combination member 20′. Afterwards, a plurality of fasteners 53′ are applied on the positioning portion 52′ for fastening the fixation member 50′ with the corresponding combination member 20′, metal member 10′, and connection member 30′. Therefore, each combination member 20′ is fixed by the two fixation members 50′, achieving the structural stability of the building material structure 200.

In addition, referring to FIG. 11 to FIG. 13, a composite material based building material structure 300 is provided in accordance with the fourth embodiment of the present invention, comprising a metal member 10′, two combination members 20′, a connection member 30′, and two fixation members 50′. The difference between the third embodiment and the fourth embodiment lies in that a sectional profile of the combined two combination members 20′ in the third embodiment is formed in a rectangle shape, and a sectional profile of the combined two combination members 20′ in the fourth embodiment is formed in a non-square rectangle shape. Thus, a width of the building material structure 300 is increased, providing a variation in usage.

Further, referring to FIG. 1, FIG. 8, FIG. 13, and FIG. 14, an assembled-type trellis is formed by the building material structures 100, 200, 300 according to different structural and functional properties thereof. When the building material structures 200, 300 are used as pillars of the trellis, the building material structures 200, 300 further comprise two covers 60′, respectively. The cover 60′ is configured to enclose an end of the combination member 20′, such that each metal member 10′ is not exposed from the combination member 20′, and decorations for the building material structures 200, 300 are also achieved. Notably, life spans of the building material structures 100, 200, 300 are increased by a combination of the metal member 10, 10′ and the combination member 20, 20′. Furthermore, the combination groove 13, 13′ of the metal member 10, 10′ provides a space for housing configuration of wires and pipes; therefore, electrical equipment, such as illuminating lamp, pretimed controller, and spraying system, is able to be mounted on the combination member 20, 20′ of the building material structures 100, 200, 300, so as to facilitate a smart and safe operation for electrically controlled illumination and spraying. Thus, combinations of the present invention possess various usage potentials.
